Looking for a new flat

Hi there :) I am a neuroscientist geek looking for a flat in London. I am sociable and funny, but I also enjoy time by my own, do a lot of reading and traveling. I am looking for a nice house, where to relax when I finish to work and have a nice chat with people. I would prefer to have mature professional, with similar schedule, who are respectful and clean. I love cats (but I don?t have any with me), so if you have one that?s a plus for me.
